Background: Glucocorticoids have several benefits in large animal medicine but apart from their benefits, there are several disadvantages attributed to the use of these drugs. Among the disadvantages, disturbance in protein metabolism is one of the side effects of glucocorticoids which has been investigated in human and laboratory animals. OBJECTIVES: There are no information regarding the effe...

Birds primarily rely on fat for energy during fasting and to fuel energetically demanding activities. Proteins are catabolized supplemental to fat, the function of which in birds remains poorly understood. It has been proposed that birds may increase the catabolism of body protein under dehydrating conditions as a means to maintain water balance, because catabolism of wet protein yields more to...

An important role in ensuring the functioning of respiratory chain belongs to cytochrome part, which includes complexes III (ubiquinol-cytochrome c oxidoreductase) and IV (cytochrome oxidase). The key components these enzymatic are heme-containing cytochromes, number depends on balance heme synthesis catabolism. δ-Aminolevulinate synthase catalyzes first step biosynthetic pathway, while oxygena...

Autophagic (lysosomal) and proteasomic protein degradation are important regulatory mechanisms in the homeostasis of muscle mass, that may be profoundly disturbed in cancer and other wasting syndromes. Due to the inhibiting effect of amino acids and insulin, net proteolysis is restricted to the fasted state, and in autophagy certain amino acids have been identified as 'regulatory' in the rat, i...
